What are the key features of MMS-122-02-L-DV?
- 44-position dual-row 2mm pitch socket strip with both top and bottom entry options for flexible PCB connector assembly
- Gold (10µin) over nickel (50µin) mating contact finish delivers reliable low-resistance connections in repeated insertion cycles
- Vertical surface mount orientation with 1.76-inch body length provides high signal density in industrial and consumer PCB designs
What is MMS-122-02-L-DV used for?
The MMS-122-02-L-DV is a versatile 44-position socket strip used in industrial control boards, data acquisition systems, and embedded computing platforms where reliable 2mm pitch board-to-board or wire-to-board connections are required. The dual top/bottom entry feature allows engineers to choose the mating direction that best fits their enclosure and cabling layout without changing the PCB footprint. Its surface mount vertical design and standard 2mm pitch make it a reliable choice for modular instrumentation and automation equipment.

Frequently Asked Questions
What makes the dual top and bottom entry feature of the MMS-122-02-L-DV useful in system design?
The dual entry (top and bottom) feature allows cables or mating headers to connect from either direction on the same 44-position, 2mm pitch socket footprint, giving engineers layout flexibility without requiring a separate PCB design revision or additional connector variants when enclosure constraints change.
How does the 2mm pitch of the MMS-122-02-L-DV compare to finer-pitch alternatives for industrial applications?
The 2mm pitch provides wider contact spacing than 1.27mm or 0.050-inch pitch alternatives, resulting in higher current-handling capacity per pin (typically 1A to 3A) and greater resistance to mechanical stress and vibration, making MMS-122-02-L-DV a preferred choice for industrial control and rugged embedded systems over finer-pitch connectors.
What PCB footprint length does the MMS-122-02-L-DV require for a 44-position dual-row layout?
The MMS-122-02-L-DV body is 1.76 inches (44.7mm) long and 0.157 inches (3.99mm) wide, housing 44 positions in a dual-row arrangement at 2mm pitch, which translates to 22 positions per row with a contact-to-contact spacing that supports standard 2mm pitch PCB land patterns.
